Description

Catheters based electromagnetic actuating device and method for medical procedures

The present invention relates to an electromagnetically driven surgical apparatus and method for a medical procedure having a catheter base. More specifically, the electromagnetically driven rotor and the catheter-based micro drill tool accurately and safely enter the stenosis vessels of the body and the electromagnetic drive system. It is possible to easily change the direction and extension by entering, and to safely control the expansion and contraction of the balloon part in the stenosis vessel, to remove the constriction by the drill tool and to suck out the particle fragments by the suction part to discharge to the outside It relates to a catheter-based electromagnetic surgery surgical apparatus and method for medical procedures.

Among cardiovascular diseases, chronic stenosis (CTO), in which the vascular lumen is completely closed by deposits and prevents blood flow, is found in 52% of patients with severe coronary artery disease.

In general, chronic complete stenosis is caused by the deposition of lipid-rich cholesterol on the inner wall of the blood vessels, resulting in occlusion of the lumen of the vessels.

The multilayer lipid and thrombosis complex constituting the stenosis lesion thus formed is replaced with collagen, etc., over time, and these collagen form a multi-molecule mass from a single molecule, crosslinking reaction and calciumation (calcification). ) To form a mechanically stable phosphorylated layer that prevents blood circulation.

As a treatment method for such chronic complete stenosis, a method of reperfusion by physically decomposing the fibrin-collagen complex of the stenosis part and a method of physical perforation are used.

However, the above-mentioned physical perforation methods are difficult to penetrate the center of the lesion along the center of the blood vessel in the process of penetrating hard calcium lesions, and also angiography agent is injected into the direction of blood flow through the blockage of the blood vessel. Since it is difficult to obtain, it is difficult to secure a form of vascular development after crossing the chronic perfect stenosis, which may cause damage and perforation of the inner wall of the blood vessel during the above physical procedure.

Therefore, in the case of chronic stenosis, the success rate of vascular intervention is 95%, whereas in the case of chronic stenosis, the success rate is only about 70%.
